Overengineering
December 4, 2012
“Overengineering” is anathema to most product manufacturers. Generally, manufacturers desire to put no more time and money into a product than is necessary. They decide upon a reasonable lifespan for a product, and then they use materials and parts that, with rare exception, have been proven to last that long. They do not care to produce a product that lasts longer than the consumer desires; they do not want to invest resources where they won’t see a return.
An exception to this general rule is invoked by those manufacturing products which, if they break, will kill or maim people. Airplanes are the classic example: they’re built with multiple redundancies and with materials and parts that have been tested to last much longer than necessary. The potential for catastrophic loss of life demands this. They will use a part that’s tested to last 20 years, and replace it after ten years just to be safe.
I suspect that some observers of the MHSAA’s recent campaign to increase sports safety training for coaches and modify playing rules that may endanger participants are critical that we’re asking too much, that we’re doing more than is necessary. But frankly, that’s exactly what we intend. When it comes to participant safety, overengineering of policies and procedures ought to be our goal.
Practice Makes Perfect?

For years, leaders of educational athletics have been critical of sports specialization, citing the physical, emotional and financial price that is often paid by young people and their families as young athletes (or their parents) chase unrealistic dreams. The weight of evidence I’ve seen has made me conclude that sports specialization is good for some, but a multi-sport experience is better for most young people.
Recently I’ve read about a new challenge to the sports specialization myth. It’s called “interleaving.” It posits that “mixing things up” is a better way to train; that brains and muscles get a better workout by mixing tasks.
This is getting national attention at thedanplan.com which chronicles a 30-something commercial photographer, Dan McLaughlin, who quit his job in Oregon with the goal of becoming a top-level professional golfer. He had read in Malcolm Gladwell’s Outliers that 10,000 hours of practice would gain him international expertise.
Along the way on this quixotic journey, Dan McLaughlin not only has been testing the 10,000-hour theory, he’s been testing interleaving – mixing lengths of putts during putting practice, mixing different types of shots on the driving range, etc.
Time magazine reported in April that this has the attention of UCLA’s Learning and Forgetting Lab which is testing the Florida State University theory popularized by Gladwell, and is searching for “the biological sweet spot.”
FYI: McLaughlin has not yet qualified for the PGA tour. But on the other hand, he still has about 4,000 practice hours to go.
